32b/64b RISC-V 5-stage, scalar, in-order, Application Processor. Linux and multi-core capable. Maps upto ARM A-35. Optimal PPA.

Overview

InCore Calcite is a 32/64 Bit RISC-V in-order, single-issue 5-stage pipelined micro-processor. Built on Incore's proprietary deep-customization stack for microarchitectural exploration, Calcite delivers an optimal balance between power and performance in an exceptionally small silicon footprint.

The Calcite core comes bundled as a compute subsystem, with integrated AMBA protocol interconnects (supports AXI4, AHB) and uncore components (PMU, debug, interrupt controllers etc).
